HOW THIS WORK CAME TO BE:
This Emergency Manual has a long history, evolving from decades of prior work on both Crisis Resource Management
(CRM) concepts and cognitive aids for critical incidents. The 1994 book entitled ‘Crisis Management in Anesthesiology’ by
Dr. David Gaba, Dr. Steven Howard, and Dr. Kevin Fish provided the initial foundations for this project. Their simulation
group has been involved in developing cognitive aids for operating rooms in the Palo Alto VA and then a national VA
project, each with bulleted points for many critical events. Observing that practitioners often miss key actions under stress,
Drs. Harrison and Goldhaber-Fiebert along with Dr. Geoff Lighthall, Dr. Ruth Fanning, Dr. Howard, and Dr. Gaba
developed several iterations of pocket cards for perioperative critical events, including some with rhythm strips, icons, and
color design. In 2004, Dr. Larry Chu conceived of adapting crisis management cognitive aids to a more visually striking
format for a new book he envisioned for today’s highly visual millennial learners. This became The Manual of Clinical
Anesthesiology, published in 2011. To create the current Emergency Manual, the Stanford Anesthesia Cognitive Aid
Group was formed. All team members have had integral roles. Dr. Larry Chu, who directs the Stanford AIM (Anesthesia
Informatics Management) lab provided the new graphics and layout, applying his design skills and an understanding of
user interface to make the content more easily usable. Drs. Sara Goldhaber-Fiebert, Kyle Harrison, Steven Howard, and
David Gaba worked jointly to provide the content, including exact phrasing, ordering, and emphasis, as well as iterative
simulation testing to revise both content and design elements. Observing how cognitive aids are used by teams during
hundreds of simulated crises has been crucial for pilot testing throughout. We hope that this Emergency Manual will
support both education and patient safety efforts. Effective use has included pre-event review, post-event team debriefing,
and ‘during’ critical event managementthe latter particularly after adequate help has arrived or when the patient is
sufficiently stable for a clinician to pause from acute care actions. We encourage the use of this Manual and welcome
feedback from all practitioners.
Acknowledgments: We appreciate the faculty and residents at Stanford and VA Palo Alto anesthesia departments for
their support of the development and implementation of the emergency manual. We are especially grateful to our chair,
Dr. Ron Pearl, for helping us make this project a reality. We are grateful to Barbara Burian for her expertise in human
factors and cognitive aid design reflected in the design of Version 3. While references are not written on each event for
space, we have tried to integrate the most pertinent clinical information from published literature for each event, including
practical publications e.g. A-ACLS modifications to AHA ACLS algorithms, ASA difficult airway algorithms, ASRA LAST
guidelines, MHAUS poster, and appreciate the work of their developers. We thank all our colleagues from the Emergency
Manuals Implementation Collaborative (EMIC), a global group fostering the dissemination, implementation, and effective
use of emergency manuals to enhance patients’ safety. Join EMIC at www.emergencymanuals.org.

3. Connect gas sampling adaptor to allow monitoring of
respiratory gases:
Is the patient receiving 100% oxygen?
4. Maintain anesthesia (if necessary) with IV drugs
1. CALL FOR HELP.
2. CALL FOR CODE CART?
3. INFORM TEAM.
SECONDARY
1. Reduce O
2
flow rates to minimum needed to conserve oxygen.
2. Obtain extra backup sources of O
2
.
3. When patient more stable, contact Bioengineers to alert them to
problem and enlist help with machine diagnosis while you focus
on patient.
4. Inform OR leadership, ICU, hospital of potential large-scale O
2
problem.
5. Discuss with surgeon implications of O
2
failure for this patient’s
management and OR schedule.

3. INFORM TEAM.
TREATMENT
1. Increase to 100% O
2
, high flow.

POWER FAILURE
By Stanford Anesthesia Cognitive Aid Group
IMMEDIATE LIFESAVING ACTIONS:
1. Get additional light sources:
• Laryngoscopes, cell phones, flashlights, etc.
2. Open doors and shades to let in ambient light.
3. Confirm ventilator is working and if not,
ventilate patient with Ambu
TM
bag and switch
to TIVA.
4. If monitors fail, check pulse and manual blood
pressure.
5. Request Transport Monitor or defibrillator
monitor.
6. Confirm adequate backup O
2
supply:
• Power failure may affect oxygen supply or
alarms.
7. Check extent of power failure:
• Call bio-med or engineering.
• Is the problem in one OR, all ORs, or hospital-
wide?
• If only in your OR, check if circuit breaker has
been tripped.

TOTAL SPINAL ANESTHESIA
By Stanford Anesthesia Cognitive Aid Group
SIGNS
AFTER NEURAXIAL ANESTHESIA BLOCK:
1. Unexpected rapid rise in sensory blockade.
2. Numbness or weakness in upper extremities (check hand
grip).
3. Dyspnea.
4. Bradycardia.
5. Hypotension (or nausea/vomiting).
6. Loss of consciousness.
7. Apnea.
8. Cardiac arrest.
1. CALL FOR HELP.
2. CALL FOR CODE CART.
3. INFORM TEAM.
TREATMENT
1. If Cardiac Arrest: Start CPR, immediate epinephrine, Go To
appropriate ACLS event.
2. Support ventilation and intubate if necessary.
3. Treat significant bradycardia or hypotension with immediate
epinephrine (start 10-100 μg, increase as needed). If mild
bradycardia, consider atropine (0.5-1 mg), but progress quickly
to epinephrine if needed.
4. Give IV fluid bolus.
5. If parturient: Left uterine displacement, call OB and
neonatology, prepare for possible emergent C-section, monitor
fetal heart rate.
